BEATING ENGNE.

Application led January 29, 19km.i Serial No. 354,992.

To all 'whom t may concern.'

Be it known that I, JUDsoN A. DE Cnw, a citizen of the Dominion of Canada, residing at Mount Vernon, New York, have invented new and useful Improvements in Beating Engines, of which the following is a specification.

This invention relates to beating engines used in the making of paper and its object-is to devise a beater that is smaller or covers less ioor space than is usual and at the same time one that is more eflicient in its treat ment of the paper stock.

To this,end the invention consists in a. vat provided with the usual beater roll and a mid-feather co-acting with the roll, but the elements are so arranged that the circulation of the stock to and from the roll is in a vertical plane instead of in the usualhorizontal l5 plane and a further important feature is that the roll is used to elevate the stock and to change the direction of the flow. 'Moreover, the mid-feather is arranged substantially horizontally and adapted to have the stock pass t-herealong and therefrom by gravity. This arrangement reduces the retarding action of friction between the stock and the sides of the vat to a minimum.

I have illustrated the preferred embodiment of my invention in the accompanying drawing in which Figure 1 illustrates a through my machine, and

Fig. 2 shows a plan View. lfn the drawings, the numeral l1 indicates the vat having sides 12 and v13. 14- indicates a straight end and 15 an end curved to cor; respond with the curvature of the beater roll 16. Between the roll 16 and the straight end 14, a mid-feather 17 extends substantially horizontal but inclined slightly downwardly and has at its end adjacent the roll 16 a dezfiector extension 18 substantially triangular in cross section. The free end 19 of the midvertical section feather is sufficiently spaced from the straight end 14 of the vat to permit thefree passage of the paper stock therebetween. Means for adjusting the degree of inclination of the mid-feather may be provided such as the screws 20 co-acting with extensions 21 on the mid-feather to raise and lower it about its pivot 22` ln operation, the paper stock passes Aunder the mid-feather 17 until the deflector guides it toward and under the roll 16 where it is duly acted upon by theroll and its co acting' parts.'l lt is then elevated by the roll and depositedon top of the mid-feather 17 where its tendency is to accumuiate. rlfhis accumulation tends to push the stock along the incline of the mid-feather until it falls off rthe end thereof due to gravity'5 to the bottom of the vat where it ows along to ward and under the roll again. The defiector extension 18 is for directing the returning stock directly to the beating point of the roll instead of letting it contact with the knives before they reach thel beating point. In this way, unnecessary friction with the downwardly moving knives is'prevented and less power is required to drive the roll.

Where the circulation of the stock is horizontal, the entire force for the circulation must be supplied by the roll., Further, the retardation of the stock flow varound the mid-feather at the ends of the vat is considerable. ln the present invention, the roll only elevates the stock and gravity 4is depended upon to complete the circulation, which results in a decided saving in power and the vertical arrangement of the io'w makes possible a vat of normal capacity but which takes up much less door place than normally. feather is made adjustable to suit different consistencies of stock.

W hat I claim is:

1. A beating engine having a vat, a beater roll at one end thereof, a substantially horizontal mid-feather extending from the roll toward the opposite end of the vat, and a substantially triangular defiector adjacent the roll, depending from the mid-feather.

lThel inclination of the inid- 2. A The device'of claim 1 in which the face of the defiector nearest the roll is curved similar to the roll and covers the vertical part ,of the roll. y f

3. A beating engine having 'a vat., a beater roll providing between-the vat and the roll a beating point, knives on said roll, and

means for preventing the knives from exertthe beating point and keeping the stock out ing a vertical', downward force upon 'the` of Contact with the knives during their verstock in the vat. tical downward movement. 10 4.- A beating engine having a vat, a beater iin testimony whereof, I have signed my 5 roll providingbetween the vat and the roll a name to this specification this 19th day of beating point, knives on said roll, and means January 1920. for directing the stock in the vat directly to JUDSON A. DE GEW.
